IMPRovEMENT IN MouSE-TRAPS.

The Schedule referred to in these Letters Patent and making part of the-sanneA To all whom Nimoy concern:

Be it known thatl I, J oHN N. BUN-NELL, of Un ion'- ville, in the county of Hartford andState of Connecticut, have invented a new and useful Improvement ill Mouse-traps, ot which the following is a full, clear, and exact description, reference being'had to the accompanying drawing forming part of this'specilication, and in l whichlfigure Trepresents a plan ot' my improved mousetrap when s et; and

Figure 2, a sectional elevation of the same, taken through its center in direction ofthe length ofthe spring-bow.

Similar letters of reference indicate correspomling parts.

The invention, which is here shown as applied to a v block-trap, but is also applicable to others, and is not confined to a single-holetrap,consists-in a lcerta-in combination of an automatic setting-strap or lever and the ordinary spring-bow and choking-loop, for opel'- ation in connection with a swinging bait-hook, whereby all nicety of adjustment vin setting the. trap, as requisite with the customary loose setting-wire having lat# eral play, isfdispensed with, and an autonlaticl settiiig-- action secured to the trap bymea-ns of the set-tingstrap or lever on its heilig borne down and made to bear or keep down the spring-lion', automatically fallinginto lock with the swinging bait-hook.

In the accompanying drawing- A is the body of a single-hole block-trap, b being the entry aperture thereto;

S is the ordinary spring-bow; and

E, the choking-loop ealried by the free end ot' the i how.

C is the swinging bait-hook. i All of these elements are common to other traps;

but instead of "us-ing a loose setting-wire, free to' hc` thrown over laterally or to rook in all directions, as in other traps, and which is both tedious-and difficult to adjustinto lock with the bait-hook, and liable to becomel accidentally disconnected from loc'k therewith, I employ a setting-strap or lever, D, hung on a suitable fulcrlnn or fulcro-,0, whereby said strap or settihgdevice is restricted as regards lateral play, and has a leverlikeaotion secured to it in direction of the length of thc'spring-bow S, whioliit serves to hold down by bearing on or over the free end oi' 'said bow,and, in being Apressed down automatically and without any other manipulation .or particnlarity of adjustment, falls into lock with the swinging bait-hook C, or the latter drops into lock with said lever or strap D, thus setting the trap expeditiously and securely.

Forward pull on the lower portion ofthe bait-hook, asl produced bythe act oi' uibbling or lattempt to detach the bait,rcleases the trap from its set, causingthe bait-hook to` ldetach itself from the setting-'strap or lever D, whereupon the spring-bow S and chokingloop E are free to ily up bythe action of thexspring as applied to the bow, and which also controls tile settingstrap or lever, holding it against heilig aceidci'itally released when in look with the bait-hook.

"liat is here claimed, and desired to be secured byv Letters-latent,isi The combination ot' the automat-ic setting-strap or lever l), constructed substantially as shown and described, and spring-bow S,'wit11 the choking-loop E,

for operatonin connection with the bait-hook, as

specilicd.
